Polypropylene film for capacitor (013)
Type: plain film and rough film for metallizati...
Place of Origin: Anhui, China
manufacturing high quality Polypropylene film for capacitor with big supply capability and shorter lead time
By adopting the imported super high-purity capacitor-grade home-polypropylene resin, the film is made by biaxial-orientation tenter process.The film features excellent profile evenness, high BDV and high mechanical strength. The winded capacitors take on the characteristics of low dielectric dissipation and high insulation resistance.
M-PPMainly for metallized-film capacitor.
S-PPMainly for foil-film capacitor.

Film thickness code
The nominal film thickness is indicated by its central value (integer value, e.g. 5,6.7 the first f
igure after decimal or its codes. The nominal film thickness of this company is the Mechani-
cal Method Value (MMV) under 10 layers testing.
